10 dpo? Odd symptoms help?

I tested @ 8 dpo BC I couldn't help myself lol got a (-) which I kinda expected. We I have had consistent light cramping only lasting a few minutes last few days & my nipples are sooooo sensitive. Now today I was in grocery store & randomly became nauseous, I somehow didn't end up getting sick but had instant heart burn within seconds of it happening. This has continued this evening. Any ideas im not gonna test until I kiss AF on 6/23, but r these even symptoms. With my first child I was sick day in/day out & my second not sick at all. So I'm very unsure. I just feel so queasy 😨 Opinions please!! Thank you
